Edge of a Voronoi diagram Assigned color of the receiver. cell the edge belongs to Begin and End voronoi vertex CCW next edge whithin voronoi cell CCW previous edge whithin voronoi cell Rotated CCW next edge whithin voronoi cell Rotated CCW previous edge whithin voronoi cell Twin edge Returns true if both vertices are finite Returns true if the end vertex is infinite Returns true if edge is straight Returns true if edge is curved Returns false if edge goes through endpoint of the segment site Returns true if edge goes through endpoint of the segment site Returns a geom representation of the edge (line segment or arc of parabola) Returns the distance of the vertices to the input source
